Precision grinding takes very small depths of cut at a fast feed rate. The action is more of a polishing/rubbing action than stock removal. The specific energy (the energy required to remove unit volume of material) is high, and more of that energy transfers into the workpiece surface. It takes over 200 sec to remove 1 in.3 (16.4 cm3 of material.
